QBO is very limited in what you can do, unlike desktop, why is anyone's guess.
The PO has another problem too, has existed for over a year now, if you use the SKU field on the PO, it shows on screen but does not print.
If you used desktop in the past this is a non partisan comparison of QBO vs QB desktop
